You can see feathers and swords fly in the intro scene -> First clue.
After that, during the transition scene, you see the dreamcatcher catching the blue feather and dodge the red sword (plus, i put a thumb up blue on top of the feather and a thumb down red on top of sword). -> Second clue.
Always in the transition scene, you can see the feather go on top of nightmare (wich is represents by a big bad black shadow) and make it fade out. -> Third clue.
Anyway i suppose you play and understand by yourself how the game is winnable, even if you miss the clue i create ;).
Thanks a lot for the test and for the message.
